Cross Sectional Area Of Rod

This 3872 lb load is acting on the 4646 in 2 cross sectional area.
Cross sectional area of rod. The cross sectional area is a π r 2 π d 2 2 π 4 d 2 a π 4 15 mm 2 225π 4 mm 2 the area is approximately 176 71 mm 2. Calculate the cross sectional area of rod 1 and the normal stress in the rod. Determine the cross sectional area for the pin at b and the average shear stress in the pin.
Stress in the connecting rod at this location is 3872 lbs 4646 in 2 8334 lb in 2. Determine the factor of safety of the rod with respect to its yield strength. Likewise the tensile force at the big end of the connecting rod at tdc can be calculated.
A force of compression in the rod will not be maximum at mid section because it is of non uniform area of cross section. The area of cross sections have unique formulas depending on the solid. Therefore a material with a fatigue endurance limit greater than 8334 lb in 2 is required.
To calculate the cross sectional area of a plane through a three dimensional solid you need to know the precise geometry of the solid and the angle the cutting plane makes with the solid s axis of symmetry if any.
